Abstract

The utility model relates to a portable conversion socket, comprising a body having pins on one end for supplying main power, and inserting pores for inserting plug, characterized in that the socket further comprises a USB conversion socket, having a first plug capable of inserting into inserting pores, and a USB socket opening and a conversion circuit board. The power source input terminal of the conversion circuit board is connected with a first plug of the USB conversion panel, and power source output terminal is connected with positive and negative power source poles of the USB type socket opening. The conversion socket has an independent changeable panel, a USB type socket opening capable of directly charging the USB input/output device is opened. Once the USB socket opening is worn, the panel can be directly changed without breaking the body, so that application and maintenance is more convenient.

Description

Portable conversion socket

Technical field

The utility model relates to a kind of portable conversion socket.

Background technology

Along with popularizing of electronic product, all be equipped with certain power supply adaptor with convenient charging at any time such as mobile phone, digital camera, MP4 etc. in the daily life, but present power source conversion socket mostly is simple function, only be applicable to a kind of voltage standard, at the whilst on tour of going out, because different countries, area are different to voltage request, so just need wear the socket of a plurality of voltage standards, to being gone out to bring some inconvenience.

So people have designed the multi-function travelling socket, socket is provided with the plug of a plurality of voltage standards, can be applicable to different countries and regions.As the patent No. is the multi-function jack that the Chinese utility model " multipurpose travelling socket " of ZL200520057917.1 discloses a kind of rotary type, each plug occupies 120 ° rotating disk space, as long as rotary turnplate just can be selected the pin type of needs, and is easy to use; And for example the patent No. is that the Chinese utility model " multi-functional tourism conversion socket " of ZL200620103720.1 includes jack body, the jack body bottom is provided with telescopic power pin, the jack body back is provided with omnipotent power supply transfer jack, cooperate in the omnipotent power supply transfer jack to be provided with copper sheet, the above-mentioned power pin bottom of described copper sheet when stretching out contacts.

The conversion socket of above-mentioned patent also all has an omnipotent conversion jack, can be the power pin of dissimilar electric equipment outfit standard types, but, at present a lot of electronic products and peripheral hardware all begin the USB interface of supporting that transmission rate is very fast and easy to connect, and the USB interface limited amount on the common computer, if adopt the USB switching interface, increasing then along with USB device, the power supply supply can be a problem, need one and can provide the use power supply for USB device with the power supply adaptor of USB socket, the power source conversion socket of above-mentioned patent does not possess such USB socket, has certain limitation; Simultaneously, the socket panel of above-mentioned patent (commentaries on classics spliced eye) is to be set directly on the jack body, so, jack shape and quantity on the jack body all are subjected to certain restriction, in case and the jack damage just needs to change whole jack body shell, dismounting and installation be trouble comparatively, awaits further to improve.

Summary of the invention

Technical problem to be solved in the utility model is a kind of socket panel independence to be provided at above-mentioned prior art present situation and can to use the USB socket to realize the conversion socket of power source charges.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this portable conversion socket, include body, the one end has for the pin that connects civil power, the other end has the jack that inserts for external plug, it is characterized in that: also include a USB conversion panel, has first plug that can insert jack on the body on this USB conversion panel, and have a USB type socket mouth and a change-over circuit plate, the power input of this change-over circuit plate connects first plug of described USB conversion panel, and power output end connects the positive-negative power utmost point of described USB type socket mouth.

For the ease of installation and removal, described body can be for including upper shell and the lower house that covers mutually together.

Because different equipment, its pin is different, in order to adapt to the pin grafting needs of obstructed type of charge device and power supply adaptor, can also comprise a universal surface plate, have second plug that can insert jack on the body and at least one pin holes that can insert for the attaching plug of external equipment on this universal surface plate.So, can be equipped with two or more socket panel, include as the panel of USB socket mouth, common three sockets or double end socket etc., to enlarge the scope of application of socket for conversion socket.

Compared with prior art, advantage of the present utility model is: this conversion socket has the panel that can independently change, on panel, have the USB type socket mouth that can directly charge to USB input-output equipment, in case USB socket mouth wearing and tearing, this panel can directly be changed and need not to destroy body, more convenient in the operation and maintenance, carrying for trip provides more convenient.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, be a preferred embodiment of the present utility model, this conversion socket includes a body 1 of being made up of upper shell 13 and lower house 14, the bottom of lower house 14 has for the pin 11 that can vertically stretch that connects civil power, also includes one and can be plugged on USB conversion panel 2 in the body 1, that can independently change;

As Fig. 2, Fig. 3 and shown in Figure 4, described USB conversion panel 2 include can be fixed with each other top panel 24, lower panel 25, and be fixedly set in change-over circuit plate 23 between top panel 21 and the lower panel 25, but on change-over circuit plate 23, be fixed with the USB type socket mouth 22 that sacrificial vessel has the direct charging of external equipment of USB interface, top panel 24 with these USB type socket mouth 22 corresponding positions have the through holes 22 adaptive with this socket mouth 22 size ', then be fixedly connected with first plug 21 below on the plate 25; Has the jack 12 that inserts for first plug 21 at upper shell 13 tops of described body 1, so, the power input of described change-over circuit plate 23 connects first plug 21 of described USB conversion panel 2, power output end connects the positive-negative power utmost point of described USB type socket mouth 22, when 2 insertings of USB conversion panel are on described body 1, can form a current circuit to the pin 11 of lower house 14 with input and output from the USB type socket mouth 22 of USB conversion panel 2.
